 Probably duplicate of #2740

 Seen under ubuntu Linux and qgis trunk but not under windows XP

 Steps to reproduce:

 *) create a mapset (tested with a few projected crs)

 *) in the qgis project properties choose the same crs. Not necessary to
 enable on the fly reprojection as in #2740

 *) add a few GRASS layers, at least one of them a raster

 *) if you save the project with the mapset still open the terminal will
 return


 {{{
 Warning: Object::connect: No such signal
 QgsRasterDataProvider::statusChanged( QString ) in
 /home/gio/qgis_unstable/src/core/raster/qgsrasterlayer.cpp:228

 }}}


 *) if before saving you close the GRASS mapset, then qgis will crash with

 {{{

         GDAL Error 6: No translation an empty SRS to PROJ.4 format is
 known.
 Segmentation fault
 }}}


 *) if you then try to reopen the project it will fail with


 {{{
 Project file read error: unexpected end of file at line 1 column 1 for
 file /home/gio/Desktop/teste4.qgs
 }}}
